Success With EBJD

[ElectricBlueSeanBurch]

Those are all line bred for their color.

So even though both the bay snook color morphs have been observed in nature using their different coloring in adapted forms of hiding they are still a "man made/hybrid/line bred/ un-natural" fish? There is a huge difference in "line breeding" like for the super red severums, and breeding fish with recessive genes to produce different "Naturally Occuring Colors." There is a certain amount of selective breeding to weed out poor blood lines and deformities, but as far as I know no one has altered the genetics of the jd's in any way

I wont get into the debate going on here. I think that if you get a good looking EBJD(no obvious issues) that is over 3+ inches you'll be ok. So far none of my EBJDs larger than 3" have died...

U want to get one that looks like this at 3".. here a pic of my old one at 3"

I've read a lot of theory's on where the origins of the ebjd came from. But the more I've read the more I come to the conclusion that is just a gene variation from a jd. I've read numerous times that it carries the same DNA as the regular jd aside from the blue gene which would be considered resessive. I've bred these guys a few times now, and if it were a hybrid why bred it with a regular jd when breeding for ebjd?

Although I have to say that would be a cool project to try and do some cross breeding a ebjd and another just as colorful cichlid. Now if someone does that I for sure want to see that!

OP, from what I've read (and we all know EVERYTHING we read is correct), if you are interested in breeding EBJD's, I don't think you can do it from 2 EBJD's. You need a male EBJD and a female BGJD. Then, something like 25% of fry will be EBJD. As far as I know, no one has had a successful breed from 2 EBJD's


Edit****Now that I have re-read your original post, I realized you were talking about breeding the bristle-nose's, not EBJD. Sorry about that.

Either way it's not really a debate post. Had best success with low protein food, frequent water changes, and added about a tbsp of salt to every 5 gals of water.

Sorry if I derailed your thread. It drives me nuts when people say ebjd are "natural". Feel free to pm me if you need any help. I like how you pointed out their similarities to flowehorn as far as health issues and deformity.

I believe they were jd hybridized with a cuban or escondido then line bred for color. Or something similar. I dont know for sure as I wasnt there.

Pretty sure it's been proven that they're not hybrids as the first EBJD were discovered from regular JD's that were wild caught and the guy that discovered them had a pretty well known reputation from the info I've read. Why's it so hard to fathom the idea that wild caught fish could carry these genes and spawn in the wild? If they were hybrids, don't you think you'd see some that look like the other species used? Never seen one look like a Cuban or Carpintis and I have seen crosses of both in person. Neither look anything close to an EBJD. People forget there are also gold color morphs of Dempsey's and someone from this site bred golds and EBJD's and created blue/gold morphs.

Ok. Some ebjd do not exactly look like wild jds and I'm not talking about color. Fins, body shape, head shape, etc. The DNA test commissioned by Jeff Rapps was not conclusive as it only tested the maternal DNA and that proves nothing other than the fact that the mother of the fish tested was mainly a jack dempsey.
The breeder did have carpintis in tanks with jds at his facility.
It was 1986 I think hybrids were probably more frowned upon than they are now (I was only 3 at the time so I dont know lol) so instead of telling the truth about how be created this cool looking fish he told his fairy tale and made them more acceptable as well as keeping his recipe secret for commercial reasons.
Seriously everything about them screams hybrid (to me and me only I guess).

Great example of hybrids are the Red Texas. They don't have to be bred with another fish that fades for them to turn red (CJ on this site bred a red Texas female with a pure male Escondido). But both parents have to carry the recessive gene to produce EBJD rather it be 2 blue gene carriers or 1 blue gene carrier and 1 EBJD. Furthermore, Carpintis are green/turquoise, not blue.

As for fins, body shape and head shape... the reason they don't look like them is most are deformed, but if you take the ones that are not deformed like mine or others they do look like regular JD's, just different colors.

OP, if these are active and look good it could be worth the gamble. If you're confident in that store and trust where they get their fish from, then I say go for it.
